How do i use mamth.random to generate three different results?

Like this:

Code:
math.random(1,3) == x
      if x == 1 then
            blah blah
      end
       if x == 2 then
              blah blah
       end
       if x == 3 then
             blah blah
       end
end


Pretty sure this doesn't work though.

How about:
Code:
x = math.floor(math.random(1,3));
      if x == 1 then
            blah blah
      end
       if x == 2 then
              blah blah
       end
       if x == 3 then
             blah blah
       end
end

I'll try that :3

Edit: Also, if you wanted a timer to start once something happened, how would you go at doing that? I think you aren't sposed to just do

Code:
if blah blah then
       self.timer = Timer();
end


I think that's buggy/doesn't work.

Like if the actor is crouched for more than 20 seconds, then blah blah.

Code:
timer:Reset()


And try:
Code:
      if math.floor(math.random(1,3)) == 1 then
            blah blah
      end
       if math.floor(math.random(1,3)) == 2 then
              blah blah
       end
       if math.floor(math.random(1,3)) == 3 then
             blah blah
       end
end

When you use the math.random function with Lua, does it give you a different result every time, or do you have to call some sort of randomize function?

I.e.
math.random = 5
math.random = 5
randomize()
math.random = 3

If there is no need for a randomize function, then (@Mail) your code will return a different random number every time it is called, and you might have code from two of the if-statement-blocks run.

Quote:
math.random(lower, upper) generates integer numbers between lower and upper.


No math.floor needed, no randomize needed.

So here's what I'd suggest:
v = math.random(1,3);
if v == 1 then
whatever
elseif v == 2 then
whatever
else
whatever
end

Ohh, it appears I mis interpeted what The Mind asked. I thought he meant how you could create 3 diffrent numbers with math.random

Grif is right.

Code:
function Create(self)
self.timer = Timer();
self.firsttimer = true
end

function Update(self)
if blah blah and self.firsttimer then
self.timer:Reset()
end
if self.timer:IsPastSimMS(number) and not self.firsttimer then
stuff
end
end
